BED-SPRING.

Application filed May 27, 1914.

Trenton, in the county of Mercer and State.

of New Jersey, have invented certain new and useful Improvements inBed-Springs,

of which the following is a specification.

This invention relates to bed springs and more particularly to a novelmeans for securing the edges of the woven wire fabric to the end bars ofthe spring frame.

One of the present methods of securing the edges of the woven wirefabric of a bed spring consists in turning the side edges of the fabricover a suitable length of strap metal and then riveting the strip to thehorizontal flange of the end bar of the frame. This method of securingthe fabric is objectionable, however, inasmuch as the ends of thestrands project beyond the edge of the securing strip and are liable tocause injury to ones hands in moving the spring, or to tear the bedclothing.

The present invention therefore aims to provide a securing and bindingmeans for the edges of the fabric, so constructed and secured as tocover the ends of the strands and thereby prevent such injury.

In the accompanying drawings: Figure 1 is a perspective view of onecorner of a bed spring, illustrating the improvement embodying thepresent invention. Fig. 2 is a vertical transverse sectional viewtherethrough. Fig. 3 is a group perspective view, illustrating parts ofthe device about to be assembled.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingby the same reference character.

In the drawings, the numeral 1 indicates in general one of the end barsof the spring frame, this bar being preferably of angle iron materialand including a vertical flange 2 and a horizontal flange 3. The usualbrackets 4 are secured to the edges of the flanges 2 and receive theends of the usual side bar 5. The woven wire fabric, which comprises thespring proper, is indicated by the numeral 6.

In order that the securing strip and the binding strip embodying thepresent invention may be secured to the horizontal flange 8, the saidflange is formed at suitable intervals with openings 7 for the passageof Specification of Letters Patent.

rivets in the manner which will be presently explained.

The securing strip is indicated by the numeral 8 and is preferably ofbar metal and provided at intervals in its length with openings 9adapted to aline with the openmgs 7 The b nding strip for covering thefree ends of the strands of the woven wire fabric is indicated by thenumeral 10 and is preferably of relatively thin sheet metal and providedwith a flange 11 which initially extends substantially at right anglesto the body portion of the strip. The strip 10 is also formed with anumber of openings 12 which are designed to register with the openings9.

in securing the edges of the woven wire fabric to the side bars of thespring frame, each of the said edge portions is folded over that edge ofthe respective strip 8, which is the inner edge when the strip issecured in place, and is passed beneath the strip and about the otheredge thereof, as clearly shown in Fig. 2 of the drawings. The bindingstrip is then disposed with its body portion beneath the strip 8 so asto cover that portion of the woven fabric which extends beneath theunder side of the said strip 8. The rivets 13 are then secured throughthe open ngs 7, 9 and 12 and headed and after this has been done, theflange 11 is struck down so as to cover the overturned edge portion ofthe fabric and thereby cover the ragged edge or projecting ends of thestrands. In order to permit of this being done, the strip 10 is ofcourse formed of malleable metal.

Referring now to Fig. 2 of the drawing. it will be observed that theflange 11 is of a sufficient width to entirelv cover the projecting endof the fabric and. conscquentlv. the same will be entirelv concealed andwill not be liable to cause injury to ones hands or to tear the bedclothing. It will furthe more be apparent that in striking down theflange 11 a rounded edge 1.4 isformed continuously along the securingmeans and, consequently, when the spring fabric is depressed it may rubalong this edge without likelihood of being worn through, as frequentlyoccurs when the strip 8 is the only means provided for securing the edgeof the fabric. Furthermore it will be observed by reference to the saidFig. 2, that the flange 11 may partly or Wholly cover the rivet heads 13so that there Will be no likelihood of the wire fabric catching on theseheads and becoming torn. It will also be noted that, inasmuch as theoverturned edge portion of the wire fabric is secured between the strip8 and the body portion of the binding strip 10, there will not be thelikelihood for it to wear through that there would be if this portionwere merely secured between the strip 8 and the horizontal flange 3 ofthe end bar.

Having thus described the invention, what is claimed as new is:

The combination with the end bar of a bed spring frame and the wovenwire spring fabric, of means for securing the edge of the fabricincluding a strip of bar metal beneath which the edge of the fabric ispassed, the said edge portion of the fabric being folded over the inneredge of the said strip to overlap the upper surface of the strip, abinding strip having a portion disposed against that part of the edgeportion of the fabric which lies beneath the said strip, and

having a flange struck over the folded over part of the fabric to extendabove that portion of the edge thereof which lies above the strip, thefabric being folded back over the outer edge of the strip and extendingabove the said strip and the binding strip, and headed fasteningelements secured through the end bar of the bed spring frame and throughthe first-mentioned portion of the binding strip, that portion of thefabric which lies between the binding and first mentioned strips, andthrough the said firstmentioned strip, the folded over flange portion ofthe binding strip overlapping the upper heads of the said fasteningelements,

whereby to guard the fabric against engagcti ment with the said heads.

In testimony whereof I ainx my signature in presence of two witnesses.
